Powering Orbital Computing: From Watts to Megawatts
If chips are the bricks and data centers are the buildings, power is one of the essential utilities that makes them work. Computing ultimately comes down to watts: keeping a 700-watt GPU running in orbit requires an entire engineering system, from solar-array orientation and battery chemistry to bus voltage. Moving from watts to megawatts means…

Danube Drought Cuts Nuclear Output: How Satellites Support Water–Energy Risk Monitoring
On 20 August 2026, Bulgaria’s Ministry of Energy and Kozloduy Nuclear Power Plant announced that Unit 5 would be reduced by approximately 120 MW on 21 August as a preventive measure in response to the Danube’s continuing decline to critically low levels. The reduction was equivalent to roughly 12% of the unit’s approximately 1,000 MW…
